With industry data show that the sale of used excavators, construction machinery nearly 40% of the fault from the hydraulic system, about 15% of the fault from the engine. With intelligent EFI technology, can significantly improve the utilization of engine power, reduce hydraulic system power loss, so that the power system and the load better match the required power and reduce the work intensity of the engine and hydraulic components, the price of imported second-hand excavators , thereby improving the reliability of the equipment in long-term use of the whole. Although energy saving machinery market has great potential, the main engineering machinery manufacturers at home and abroad also have intelligent environment around a big fuss EFI machines, but there are industry experts have warned that the current domestic market most intelligent EFI machines are still in the product promotion the level of a third-party market data clearly show statistical agency, Hangzhou used excavators, 2014 - June before the five main domestic brand excavator (crawler) Total sales of 26,049 units, of which direct injection excavator accounting for about 71 percent, while only 29% of EFI excavator ratio. From sales data, market users and consumers still prefer the new direct-injection excavators.
